The six-member Expedition 42 crew is safe in the Russian segment of the International Space Station after an alarm went off in the U.S. segment of the orbital laboratory Wednesday morning.
Flight controllers are seeing no direct evidence of an ammonia leak and are exploring the likelihood a faulty sensor or computer relay set off the alarm.
NASA’s International Space Station Program Manager Mike Suffredini sat down with Public Affairs Officer Dan Huot to discuss today’s events. Suffredini described the crew’s response and how this morning’s situation unfolded. Watch the interview above.
The hatches to Dragon were opened for business Tuesday morning at 3:23 a.m. EST and the crew began unpacking critical gear that will support 256 science experiments. The SpaceX commercial cargo craft was attached Monday to the Harmony module at 8:54 a.m.
One experiment that was immediately set up by Flight Engineer Terry Virts was the Micro-5 study. That experiment observes microorganisms as a model for humans so scientists can understand changes in a crew member’s immune system and the risk of infectious disease in space.
The SpaceX Dragon cargo spacecraft was berthed to the Harmony module of the International Space Station at 8:54 a.m. EST. The hatch between the newly arrived spacecraft and the Harmony module of the space station is scheduled to be opened Tuesday, but could occur earlier. The capsule is scheduled to spend four weeks attached to the station.

While the International Space Station was traveling over the Mediterranean Sea, Expedition 42 Commander Barry “Butch” Wilmore of NASA, with the assistance of Flight Engineer Samantha Cristoforetti of the European Space Agency, successfully captured the SpaceX Dragon spacecraft with the station’s robotic arm at 5:54 a.m. EST.
NASA TV coverage of operations to berth Dragon to the space station will begin at 7:45 a.m.
The International Space Station and Dragon flight control teams are proceeding toward rendezvous and grapple at 6:12 a.m. EST on Monday, Jan. 12.
SpaceX reported all spacecraft systems are ready for the final stages of rendezvous, and space station flight controllers reported the orbiting outpost is ready for the commercial spacecraft’s arrival.

The Expedition 42 crew is getting ready for a delivery aboard the Dragon commercial cargo craft as well as next month’s departure of Europe’s fifth and final Automated Transfer Vehicle (ATV-5).
The weather looks favorable for Saturday’s planned launch of Dragon aboard a Falcon 9 rocket at 4:47 a.m. EST. Dragon will arrive at the International Space Station Monday morning carrying more than 5,000 pounds of supplies, payloads and critical research.
Commander Barry Wilmore and Flight Engineer Terry Virts worked on readying the ATV-5 resupply craft for it’s undocking from the Zvezda service module and departure Feb. 27. It will reenter the Earth’s atmosphere loaded with trash and discarded gear for a fiery disposal over the Pacific Ocean.
SpaceX engineers swapped out a suspect thrust vector control actuator in the second stage of their Falcon 9 rocket that halted Tuesday’ s launch of its Dragon commercial cargo craft. Dragon’s launch atop the Falcon 9 is now set for Saturday at 4:47 a.m. EST with live NASA Television coverage scheduled to begin at 3:30 a.m.
Thursday’s Expedition 42 science highlights included a pair of advanced remote control experiments inside the International Space Station. One experiment is studying the feasibility of controlling robots on the ground from space with a crew member using an advanced joystick that provides haptic feedback. The other uses bowling ball sized satellites, known as SPHERES, programmed by competing teams of high school students to accomplish tasks relevant to future space missions.
Another experiment is researching acoustic methods for locating punctures on the outside of the space station caused by human activity or micrometeoroid impacts. Crew members also studied the plasma environment in the station and photographed the ongoing man-made and natural changes to the Earth’s surface.
The six-member Expedition 42 crew had the day off and relaxed Wednesday for the Russian Christmas holiday. Meanwhile, SpaceX engineers in Florida worked to troubleshoot an issue in the second stage of the Falcon 9 rocket that halted Tuesday’ s launch of its Dragon commercial cargo craft.
Dragon’s launch atop the Falcon 9 rocket is now set for Saturday at 4:47 a.m. EST with live NASA Television coverage scheduled to begin at 3:30 a.m. SpaceX’s fifth cargo mission for NASA’s Commercial Resupply Services contract will arrive at the International Space Station on Monday culminating in the robotic capture of Dragon around 6 a.m. Live NASA TV coverage will begin at 4:30 a.m.
Expedition 42 will wait a few more days for a delivery from the SpaceX Dragon commercial cargo craft. Its launch aboard the Falcon 9 rocket was aborted Tuesday morning with one minute, 21 seconds left on the countdown clock. SpaceX is evaluating the issue and will determine the next opportunity to launch the company’s fifth commercial resupply services mission to the International Space Station. The next available opportunity to launch to the station would be Friday, Jan. 9.
Meanwhile, the six member crew stuck to its task list of science benefiting life on Earth and in space as well as advanced maintenance of the orbital laboratory.
Italian astronaut Samantha Cristoforetti participated in a study observing the aging of skin and tested an X-ray device that measures bone density in space. Flight Engineer Terry Virts opened the Fluids Integrated Rack to prepare samples for the Advanced Colloids Experiment-Microscopy-3 study. Commander Barry Wilmore conducted plumbing and ventilation fan cleaning tasks.
Cosmonaut Elena Serova deployed dosimeters for a radiation detection study and downloaded data collected from an earthquake experiment. Alexander Samokutyaev took photographs and recorded video documenting life on the station before an afternoon of maintenance in the Russian segment. Anton Shkaplerov disinfected the area behind panels in the Zvezda service module.
The SpaceX Falcon 9 launch scheduled for this morning at 6:20 a.m. EST aborted with one minute, 21 seconds left on the countdown clock. A thrust vector control actuator for the Falcon 9’s second stage failed to perform as expected, resulting in a launch abort. SpaceX is evaluating the issue and will determine the next opportunity to launch the company’s fifth commercial resupply services mission to the International Space Station. The next available opportunity to launch to the station would be Friday, Jan. 9.
